yesterday i used it but today i got some message i think its DETECTABLE

This is a message spread by EA to everyone on Battlelog... even if you have never hacked in your life on that account.
Its a "false" warning and applies to the issue known as #81568 "Origin and PB fucked up bigtime 2014" for battlefield 4.
Basicly what it is, is that Origin messed up and you can get banned without hack when playing BF4.

Detected. I opened Battlelog and this message came up:
"We are investigating a recent unwarranted PunkBuster ban. We are working to resolve the issue as soon as possible. Thank you for your patience."
If I try to join a server this comes up:
"Game disconnected: you were kicked by PunkBuster. Stated reason: PunkBuster kicked player 'SkushBoZZ' (for 5 minutes) ... Violation (WALLHACK) #60552"

Sorry I found out that You should NOT do long sessions with this hack,it crashed me before after like a 20+ minutes match while like 82/23(ty hack)
so just know out there that it is detactble,Just not too fast.
